摘要
基于微机保护的综合自动化系统在铁路变配电所得到普遍的应用。微机保护的高可靠性,使得传统的继保测试方式已经不完全适应运行的需要。通常情况下只需要测试仪器能够提供一路幅值可调的交流电流就可以满足电流传动试验的需要。为提高生产效率,减轻继保试验人员负担,讨论了一种针对变配电所综自系统微机保护电流测试的便携式小型测试仪的设计,以满足微机保护装置电流传动试验的需要。
The integrated automation system based on microcomputer protection is widely applied in railway power transformer and distribution station. The high reliability of micro-computer protection makes the traditional way of relay Protection test can＇t fully meet the needs of the operation. Usually the tester providing one way adjustable amplitude of al- ternating current can meet the needs of the current driving test. In order to improve the production efficiency and reduce the burden of relay protection testing personnel ,this paper discussed a kind of protable tester＇s designation of the inte- grated automation system of power transformer and distribution Station microcomputer protection test in order to meet the needs of the current driving test of the microcomputer protection device.
